Project Objectives
o Study service engineering in cognitive radionetworks, identifying the services that can be offered tocognitive radio users by secondary operators
o Investigate the cohabitation of primary and secondarywireless providers as well as offered services in thecognitive radio network
o Propose solutions and protocols at different layers ofthe protocol stack to allow cohabitation and to maximizethe usage/revenues of wireless operators
o Validate over an experimental cognitive radioplatform the proposed solution based on GNU radiodevices. Furthermore, test a real solution deployment in awireless provider hotspot
MÉTHODOLOGIES & RESULTS
o LICoRNe adopts an operator point of view toinvestigate the real service deployment over this noveltechnology.
o Start from the services in order to propose adaptation
at different layers of the protocol stack to allow servicesand applications to cohabit. Such approach is feasiblewith the LICoRNe consortium that has expertisespreading from physical layer to applications
Main technological breakthroughs :o Cognitive radio node architecture to handle the
LICoRNe challenges and realize defined use caseso Physical layer solution that exploits the underlay modelo Spectrum handoff technique with a clever channel
switching strategy based on required services from theapplication
o Point to multipoint reliable transport protocol forpublic safety traffic
o Decentralized management plane to convey forcognitive radio nodes required information for localdecisions
o GNU radio based cognitive radio platform thatimplements most of the previously cited breakthroughs
o 1 patent, 2 journal publications, 6 conference publications
CONCLUSION & PRESPECTIVES
o LICoRNe proposes a cohabitation framework betweenprimary and secondary operators in cognitive radionetworks
o Many developed protocols already in experimentationover a specifically deployed GNU radio platform
o LICoRNe shows that based on the consideredenvironment different services can be offered tosecondary users
o Implement the remaining protocols over GNU radioplatform representative
o TV white spaces scenario to be tested in a realdeployment over a NomoTech hotspot
